I can't find any price listed anywhere. Without knowing that, I don't feel like even starting the trial.
Goodluck, and hopefully the pricings good!
The service will cost no less than the cloud provider price where the server is running, plus a fee for us to maintain the platform up and running.
You will probably like to spin-up game servers using a web interface, rather than administering a Linux machine via ssh, isn't it?
A web interface would take a lot of hastle out id imagine, especially if game specific instances and prebuilt modules are available in a semi plug and olay manner.
Basically, you can let as many users joins as the virtual server can support them, until it starts swapping when RAM is exausted (and performances will fall down).
Edit: fat thumbs on mobile.
